What is the molarity of 200 ml of solution in which 2.0 moles of sodium bromide is dissolved?

The molarity of the solution is 10M

Explanation:

The molarity is defined by the moles of the solute per liter of solution.

So, we need to convert the given quantity of solution from mL to Liters.

Now we replace the given values in the formula of molarity:

Molarity =

Molarity = 10M

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
